I'm not so sure about that, it's not really a certification but a membership. If your membership lapses, then technically you are not a DM any more.
Well, it's not quite like being a licensed pilot wherein the hobby is regulated by a federal agency.
Let us just sat that if one was graduated from a university with medical doctor's degree, then that person IS a doctor. Now, whether or not he pays AMA dues or takes an exam in order to PRACTICE in a particular state is another matter.
If a person successfully completes the D/M course and pays the certification fee, then PADI CERTIFIES that person as a divemaster. The certification is conferred upon the applicant.
That certification card does not expire. However, to ACT IN A PROFESSIONAL CAPACITY IN A PADI COURSE, the divemaster must have current status as a PADI member and must carry the appropriate liability insurance.
What it gets down to, in the PADI world, is "practical" and "practicing", and all that goes back to $$$$$$$.
